United States Patent 2,911,711 DISPOSABLE SAFETY RAZOR John P. Loughlin,Shenandoah, Pa. Application April 12, 1957, Serial No. 652,536 1 Claim.(Cl. 30-32) The present invention relates to new and useful improvementsin safety razors and has for its primary object to provide, in a manneras hereinafter set forth, an inexpensive article of this characterwhich, if desired, may be discarded after a single use.

Another very important object of the invention is to provide an improveddisposable safety razor of the character described wherein the parts arepermanently assem'bled, thus preventing insertion of a new blade.

Other objects of the invention are to provide a safety razor of thecharacter described which will be of relatively simple construction,sanitary, of light weight and which may be manufactured at low cost.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is an elevational view of a disposable safety razor embodyingthe present invention;

Figure 2 is a perspective view of the invention, showing the partsseparated;

Figure 3 is a sectional view taken substantially on the line 3-3 ofFigure 1;

Figure 4 is a sectional view through the head assembly, takensubstantially on the line 44 of Figure 3;

Figure 5 is a sectional view taken substantially on the line 55 ofFigure 3; and

Figure 6 is a fragmentary view in vertical section through one endportion of the head assembly, showing the method of engaging the handlebooks with the blade retaining plate.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises ahandle which is designated generally by reference numeral 7. Permanentlymounted on the handle 7 is a head assembly 8.

The head assembly 8 comprises a transversely elongated lower plate orguard 9 which is preferably of a suitable plastic. Mounted on the guard9 is a double edged blade 10. Mounted on the blade 10 is a retainingplate 11 for said blade, which plate 11 is also preferably of a suitableplastic.

As shown to advantage in Figure 2 of the drawing, the guard 9 has formedin its central portion a longitudinally extending slot 12. Adjacent theends of the longitudinal slot 12, the guard 9 is further provided withtransverse slots or elongated openings 13. Adjacent to and parallelingthe cutting edges 14 of the blade 10, the guard 9 further includes slots'15 for the passage of lather, etc., from said blade.

The blade 10 is provided in its central portion with a longitudinal slot16 which is in registry with the slot 12 in the guard 9. Adjacent theends of the slot 16, the blade 10 still further includes a pair oftransverse slots or elongated openings 17 which are aligned with theopenings or slots 13.

The clamping or retaining cap or plate 11 is substantiallycrescent-shaped in cross-section and has formed integrally therewith onits concave side a longitudinal rib 18 which is engaged in the alignedslots 16 and 12. The clamping plate or cap 11 further includes, adjacentthe ice ends of the rib 18, a pair of flat ears or lugs 19 which projectthrough the aligned openings 17 and 13 in the blade 10 and the guide 9.The ears or lugs 19 have formed therein substantially rectangularopenings 20. As shown to advantage in Figure 6 of the drawing, theopenings 20 include bevelled rear walls 21.

The handle 7, which is of a suitable resilient plastic, is substantiallyU-shaped, said handle including a bight portion 22, legs 23 comprisinginwardly bowed portions 24, said legs terminating at their free ends ininturned hooks 25 of rectangular cross-section which are engageable inthe openings 20 in the ears or lugs 19. The hooks 25 terminate inbevelled free ends 26 adapted to ride on the bevelled surfaces or walls21 of the openings 20 to facilitate engaging said hooks with a snapaction for permanently anchoring said hooks in the ears or lugs 19.

It is thought that the invention will be readily understood from aconsideration of the foregoing. Briefly, to assemble the razor the blade10 is positioned on the guard 9 and the blade retaining plate or cap 11is mounted on said blade 10 with the rib 18 engaged in the slots 16 and15 and the ears or lugs 19 projecting through the registering openings17 and 13. The legs 23 of the handle 7 are then spread and the hooks 25are seated in the openings 20, as shown in Figure 6 of the drawing. Thelegs 23 of the resilient handle 7 are then compressed or forced togetherfor snapping the hooks 25 through the ears or lugs 19 in an obviousmanner, this operation being facilitated by the bevelled free ends 26 ofsaid hooks riding on the complemental walls 21 of the ear or lugopenings 20. When thus pressed in the ears or lugs 19 (see Figure 3) thehooks 25 cannot be withdrawn, thereby preventing the razor from beingdisassembled.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

A safety razor comprising: a head including a guard and a plate for thereception of a blade therebetween, ears on the plate projecting throughthe guard, said ears having transverse polygonal apertures thereincomprising inwardly and forwardly bevelled rear Walls, a generallyU-shaped, resilient handle mounted on the'head ast'raddle the ears, andinturned polygonal hooks on the ends of said handle insertable underpressure through the apertures from the outer ends thereof for snappingbehind the ears and anchoring the hooks therein for securing the guardand the plate together, said hooks including bevelled free ends slidableon the bevelled aperture walls and cooperable therewith for facilitatingthe insertion of said hooks in said ears.
